Ok here's a question. Say I've got 50 routers on a phase II only backbone. They are a mix of Fastpaths, Gatorboxes and Ciscos. I have a cable-range of 20-23, and four zone names defined. I need to add another ethernet phase II zone name. Do I need to reconfigure each and every router? Or can I just reconfigure one of the routers and have the rest "learn" i.e. seed from the newly reconfigured? I don't want to change the home zone, only add a new phase II ethernet zone name. Have any of you done this? I can't believe that I'd have to take down the whole net just to add a new zone. Thanks -Gnow Reason

The other routers got the phase 2 zone names from the seed router. I did not tell the other routers about any of the zones on the Ethertalk side they learned it from seed router. The only difference I can see between a seed router and the "other" routers is the seed router has a list of zones names, they "others" don't so they go looking for them. If you have a Kinetics or Shiva FastPath, or a GatorBox manual, they all go into how seed routers work in great detail, although I didn't quite realize why the first time I read them. -- Dan Boehlke Internet: dan@gac.edu Campus Network Manager BITNET: dan@gacvax1.bitnet Gustavus Adolphus College St. Peter, MN 56082 USA Phone: (507)933-7596

You need to configure the zone into every one of your gateways that has the zone list configured (the seed gateways), reboot those, and then reboot all of the others (which must all have been down together - really down). If everything is a seed gateway, you have it easier, you can reconfig the gateways, one by one - but don't expect any network sanity until they have all been reconfigured. If you have any gateways that aren't connected to this phase 2 net (ie: any connected through some other router which is connected) then you have an even bigger problem - you can either reboot everything or you have to leave your phase 2 net down (which basically means for this purpose, any gateway on it which connects to a net on which there is any other gateway) for long enough that all knowledge of the net you're changing to have timed out - 10 minutes is recommended, whether thats really long enough or not really depends on how complex your net topology is. Once the net has time out, the gateway can be restarted, and the other gateways (not on the net being changed) will learn the changed zone names dynamically. kre

Keep a copy of Robert's description for when you have to use it, or read page 8-22 in "Inside AppleTalk, Second Edition". Chapter 7 of the "AppleTalk Internet Router Administrator's Guide" also gives a good description. The original "Inside AppleTalk" (1989) had a full description and specification of a "Zone name changing" protocol. Quoting from that section however: "The request to change a network's zone name can originate from any node on the internet". Huh!?! I don't think anyone implemented this specification - the possibility of "Electronic Zone Graffiti" was far too likely. "Inside AppleTalk, Second Edition" (1990): "It is envisioned that future network management protocols, to be defined by Apple, will provide this functionality. It then continues to give a good description as to why this is (and has to be) the case. That's where it stands at the moment. Choose those zone names carefully - you won't want to change them. ======================== Tom Evans tom@wcc.oz.au ** ADD ".au" MANUALLY (don't trust "reply") ** Webster Computer Corp P/L, 1270 Ferntree Gully Rd Scoresby, Melbourne 3179 Victoria, Australia 61-3-764-1100 FAX ...764-1179 A.C.N. 004 818 455

"I don't want to change the home zone, only add a new phase II ethernet zone name. Have any of you done this? I can't believe that I'd have to take down the whole net just to add a new zone." We've got a phase 2 net and our approach is to just have two seed routers. (Two rather than one for redundancy.) That way, when you add a zone, you just have to bring down two routers, rather than every router on the net. By the way, it does take a while after adding the new zone for all the routers to settle down with a complete list of zones.

I've been implementing most of the lower-level EtherTalk protocols from (what I now know) is phase I EtherTalk, on a PC connected to our campus Ethernet net, to enable me to write some AppleTalk- speaking net utilities. The PC uses the Clarkson packet drivers, and the Macs on the net that the PC talks to are a combination of LocalTalk nets connected through routers and "directly" connected Macs with EtherTalk (?) boards. At any rate, I've got the protocols I need/want implemented now, but our campus will soon switch to Phase II EtherTalk, and I need to know a) the basic difference between Phase I & II, and b) a good reference book for Phase II that includes descriptions of the packet formats used in all protocols. I've been using "Inside AppleTalk" (first edition, I believe) until now, and I'd like to know if the Second Edition contains as much info on Phase II as the First, and/or if there's any other recommended texts out there I should look at. Thanks in advance for any info. < Kai Getrost > kai@pyrite.som.cwru.edu > - - - - - - - - - < kai@skybridge.scl.cwru.edu < Tweak, twiddle, > Freenet: kng2@po.cwru.edu - - - - - - - - - - - - - - - > frob, destroy!! < getrost@alpha.ces.cwru.edu > >======================== >Tom Evans tom@wcc.oz.au ** ADD ".au" MANUALLY (don't trust "reply") ** >Webster Computer Corp P/L, 1270 Ferntree Gully Rd Scoresby, Melbourne 3179 >Victoria, Australia 61-3-764-1100 FAX ...764-1179 A.C.N. 004 818 455 -- I'd call you a bestial < Kai Getrost > kai@pyrite.som.cwru.edu sodomistic necrophiliac, but > - - - - - - - - - < kai@skybridge.scl.cwru.edu that's beating a dead horse. < Tweak, twiddle, > Freenet: kng2@po.cwru.edu - - - - - - - - - - - - - - - > frob, destroy!! < getrost@alpha.ces.cwru.edu
